The war swirling around Leaving Neverland was kicked up a notch on Sunday night, after the first part of the two-part documentary made its debut on HBO. The film revolves around two men who say the late Michael Jackson abused them when they were children, and has been a source of ire for the singer’s estate over the last few weeks. On Sunday night, Jackson’s estate responded to the doc’s debut with some counter-programming, dropping Live in Bucharest (The Dangerous Tour)—a two-hour-long Jackson concert video—on YouTube.

“Don’t miss the magic from the King of Pop himself!” said Jackson’s official Twitter account, as the first part of the documentary premiered on HBO. “Immerse yourself in Michael Jackson. Live in Bucharest and Live at Wembley Stadium available for a limited time on Michael Jackson’s @youtube!”

The concert video shows Jackson at a tour stop in Bucharest on October 1, 1992, the year before he was first publicly accused of sexually abusing a child. It has racked up 168,576 views on YouTube since it was published.

Ratings for Leaving Neverland have not yet been released. Even so, it’s already one of the most polarizing, talked-about releases of the year, not least because of the reaction the film has elicited from the Jackson estate. The two-parter follows Wade Robson and James Safechuck, two men who became friends with Jackson when they were children, and both claim he sexually abused them for years. They also suggest that Jackson sexually abused numerous other boys as well, though the documentary focuses only on their claims. (Jackson denied the claims, and was acquitted in 2005 on 10 felony counts, including 4 counts of child molesting and 1 of attempted child molesting.)

The film originally debuted at the Sundance Film Festival, reportedly generating threats from Jackson fans. It was later picked up by HBO in the U.S. and Channel 4 in the U.K. The Jackson estate has responded by claiming that filmmaker Dan Reed painted an inaccurate portrait of Jackson, because he did not include a response from the estate in the film. The estate has since filed a $100 million lawsuit against HBO, citing in part that the network breached a non-disparagement clause it agreed to in 1992, when the network aired Michael Jackson in Concert in Bucharest: The Dangerous Tour—the same tour that was uploaded to YouTube on Sunday night.

Jackson’s hard-core fans have also assembled against Leaving Neverland. As The New York Times reports, they have coordinated attacks against the documentary, doing everything from flooding the #LeavingNeverland hashtag to streaming Jackson’s catalogue on as many platforms as possible. They have been encouraged by Jackson’s nephew, Taj, who recently set up a GoFundMe page to buy ads on London buses proclaiming his uncle’s innocence. The ad features a photo of Jackson and a message that reads: “Facts don’t lie. People do.” The word “innocent” is emblazoned across the singer’s mouth, and there is a link to a Web site further proclaiming his innocence.

Reed has said he’s received dozens of e-mails from Jackson fans since Leaving Neverland was first announced. Robson and Safechuck have also been threatened with violence, he told the Times. “One can only compare them to religious fanatics, really,” the filmmaker told the paper. “They’re the Islamic State of fandom.”

However, the documentary’s team isn’t being quieted by these attempts. Per Deadline, distributor Kew Media Group has since sold the doc into 130 territories, expanding its reach even farther.
